Serial No. 170,453.

To It]; whom it 71mg concern:

Be it known that I, GIDnoN KLAY, a citizen of the United States, and a resident of Bluffton, in the county of Allen and State of Ohio, have made a certain new and useful Invention in Door and 'indow Screens; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 is a view of the invention applied to a screen-door. Fig. 2 is a vertical section view of the same on line 1 1 of Fig. 1. Fig. 3 is a perspective view of the invention.

The invention relates to screen doors and windows; and it consists in the novel construction and combination of parts, as hereinafter set forth.

In the accompanying drawings, the letter a designates the framing of the screen, and 7) the wire-cloth attached thereto.

0 represents a small fly-passage tube which is designed to be used in connection with the screen in order to allow a fly to pass outward from the apartment, while obstructing the return of the insect. The device consists of a flattened tapering tubular portion (Z and a flange (1', being an extension of the flattened top portion. The device is designed to be made of sheet metal bent in form, as shown at It has a plane bottom wall which is connected by side walls to a plane top wall which is extended at the larger portion of the tube to form the plane attachment-flange a, which is inclined outward at an obtuse angle to the plane top wall of the tube, as shown. The flange a is perforated at ii for attachment to the lower surface of the frame-bar, which being horizontal will cause the tube to be inthe inner surface of the screen, as shown in Fig. 2 of the drawings. The device is then fastened to the frame-bar by means of a tack through its attachment-flange, which is in contact with the frame-bar. \Vhen so fastened, the relative inclination of the flange and tube causes the latter to be directed a little upward and outward in an inclined manner, so that a fly crawling upward and along the upper portion of the screen will be directed by the frame to the wider opening of the tube and will pass through it out of the apartment. The smaller 1 opening at the outer end of the tube in its projected position beyond the outer surface clined upward and outward from its wider to its narrower end.

To apply the device, the mesh of the screen adjacent to the frame is widened and the flatthrough the opening sufliciently to bring the inclined margin of its wider end flush with i of the screen and almost entirely above the lower edge of the frame-bar serves to obstruct the passage of these insects inward. As the passage is broad, it is suitable to the general form of the insect, and having a plane top wall the attachment extension thereof is strong and holds the tube effectually in inclined position. The slope of the margin of the wider opening of the tube is at right angles to the plane of the attachment-flange, so that when the latter is secured to the frame-bar the margin of the tube will be in the vertical plane and, as hereinbefore stated, flush with the screen-surface.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isp In afly-screen, an integral metallic horizontally-flattened tapering fly-passage tube, having a plane top wall and a plane bottom wall a sloping entrance-margin, and directly extending from the top wall at the entrance a perforated attachment-flange forming an ob tuse angle with the plane top wall and a right angle with said sloping entrance-margin, whereby its entrance-margin will be flush with the screen-sur face when the flange is attached to the screen-frame, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
